I had a orange-blooming trumpet vine for 15 yrs or so. My son gave it to me when it was just a tiny stick with 3 root hairs. I planted in front of a split-rail fence with a garden fencing liner. I grew by leaps and bounds, blooming in the 3rd year.
It was a love-hate relationship. I loved it because the flowers were beautiful and the hummingbirds loved it. I also saw hummingbird moths for the first time hovering around it.
HOWEVER--it was very invasive! I constantly had to pull out suckers from the flower bed and yard. The suckers also invaded the neighbors' yard on the other side of the fence.
It looked more like a tree than a vine. It had 4 thick "trunks" intertwined into the fence. The leaves and flowers were a canopy 12-15 feet up.
